New SecureChem™ IBC Level Control & Chemical Transfer system

H+E has recently commissioned a new SecureChem™ IBC chemical dosing and chemical transfer system for two chemicals from a client in the Pharmaceutical sector.

A pre-assembled SecureChem™ chemical dosing system for two chemicals before delivery to site

Many of H+E’s clients dose chemicals from Intermediate Bulk Containers. Some have commented about the amount of chemical they waste. This problem is really because there is no level control included within IBCs to advise when the IBC is empty. Also, when using chemical 24/7 it is impractical to have an operator standing by the IBC ready to change it immediately once it is empty. This is especially true at weekends. Even if you did that, there is still a substantial time when the chemical is not available. This is because you have to:

  • Disconnect the empty IBC and remove it
  • Replace it with a new one and then connect it.

H+E therefore developed its SecureChemIBC chemical dosing system to address these issues. Our clients use SecureChem™ systems to work with a range of chemicals. This ranges from standard dosing requirements to rather unusual needs, including dosing of tartaric acid.

System allows non-stop 24/7 operation

The system basically provides an external level control with a “buffer” volume of chemical. An alarm is generated when there is no more chemical leaving the IBC whilst maintaining flow to the point of use. You can connect two IBCs to the system on a “duty / standby” basis, with automatic valves that automatically change the on-line IBC. The system also generates an alarm to advise that the empty IBC should be replaced.

You can also have a system with a single IBC connected, perhaps if chemical consumption is low and only periodic.

You can also have either single or duty & standby chemical transfer pumps

The enclosure around the level control system provides weather and frost protection. Obviously, the location and weather conditions determine if this is necessary. Also, the chemical IBCs can be located inside enclosures.

In this particular case, the system is located outside and handles two chemicals, with duty and standby IBCs.

The Level control unit is inside an enclosure and the IBCs have electrically-heated jackets.

Dual-contained pipework  transfers the chemicals inside the factory to “Point of Use” tanks.

Biological treatment of 600 m³/h paper pulp wastewater in Bulgaria

H+E, one of the leading international designers and suppliers of industrial process and wastewater treatment systems, has received an order for a new biological wastewater treatment plant. Svilocell, a Bulgarian viscose pulp producer has to meet the future EU-imposed discharge limits into the River Danube. To achieve this, H+E will provide expansion by adding biological treatment to the existing purely mechanical wastewater treatment plant.

H+E’s Long Experience

Svilocell ultimately decided to work with H+E due to the company’s many years of expertise. We have designed and built nearly 80 plants for the pulp and paper industry. Those long-term customers have also expressed their very positive experiences! Another positive factor was that H+E’s design allows the new process steps to integrate compactly into the existing plant layout. This utilises the available space efficiently.
The wastewater is first cooled in an indirect cooling system to the temperature compatible with the biological process. A mechanical cleaning step then removes solids before the wastewater  transfers to the new two-stage biological purification. The balanced combination of the BIOFIT®.H floating bed and the BIOFIT®.C aeration results in a cost-optimised solution.

In particular, the AEROFIT.V ventilation system contributes to the intrinsic value and energy efficiency of the new wastewater treatment system. It allows trouble-free operation over a period of decades with a consistently high oxygen yield.
Biochips with an especially high specific growth area are used as biofilm carriers.

The chosen process line will equip Svilocell with a highly robust and efficient wastewater treatment facility from 2018 onwards, in order to fully meet the requirements for environmental protection.

Wide range of available Technologies

H+E also offers other process technologies for the pulp and paper industry, such as the cost-effective and energy-efficient mechanical treatment FLOCOMAT®.T and, for tertiary treatment, the BIOFIT®.Oxyd2 or FLOCOPAC® processes to reduce resistant COD.

Long-Term Support

H+E has always offered Long-Term Technical Support, Servicing and Spare parts to every client. In many exceeds 25 years, demonstrating the long life of our designs. We also offer the same service to you if your plant was supplied by another company. Please just contact us and we will be happy to talk to you about your needs.

Major Upgrade for Biological Wastewater Treatment Plant

H+E recently modernised a biological wastewater treatment plant for Knauf Petroboard AG in Russia. Completing this project together with our Russian subsidiary, OOO H+E Rus, enabled us to provide a complete package to the client.

The Project

Modernisation of the wastewater treatment plant at “Knauf Petroboard AG” was necessary to ensure improvement of the quality of treated wastewater. As a result, we therefore ensured protection of fishing waters into which it discharges.

The client chose H+E for this contract for a number of reasons, including:

  • Its many years of experience in treating this type of waste.
  • The presence of its subsidiary OOO “H+E Rus”
  • The proposed process concept for the renewal of the wastewater treatment plant.
  • H+E’s ability to undertake the modernisation of the wastewater treatment plant.
  • To guarantee the strict limit values for purified wastewater discharged into a fishing river.

All this was done at the same time as the client re-built a board manufacturing machine.

The Scope of Supply

The modernisation of this plant included the following major changes:

  • Installation of two new drum screens and two FLOCOMAT®.T clarifiers.
  • Converting the two existing pre-clarifiers into a combination of BIOFIT®.H high-load and BIOFIT®.SC low-load biological treatment stages.
  • Expanding the ventilation station. This included retrofitting the existing second-stage aeration tanks with a new AEROFIT®.V ventilation system.
  • Installing a disinfection plant upstream of the purified sanitary water discharge into the river.

These changes therefore represent a compact solution, already been widely tested in the paper industry on many occasions.

Furthermore H+E installed a further modernisation step, a so-called tertiary cleaning stage. It consists of two lines:

  1. A BIOFIT®.HAC floating bed with powdered activated carbon dosing system.
  2. A FLOCOPAC® high-performance contact sludge inclined-plate clarifier.

It is installed upstream of the UV disinfection system. This important addition ensured that could therefore achieve the required low discharge values.

Integrating already existing components of the plant also reduced the investment cost; another advantage.

Water & Wastewater Treatment for Printed Circuit Manufacturer

H+E has been a leading international supplier of industrial water & wastewater treatment systems for many years. We have a reputation for both innovation and very high quality.

This, combined with the long-term technical support and service we provide, is of great importance to our clients. You stand a real risk of having to stop production if your wastewater treatment plant does not work properly. If the problem is not solved quickly, this is a real potential business risk! Hence, you need a plant that is

  • Well designed.
  • Carefully constructed to a high standard.
  • Meticulously installed.
  • Regularly serviced.

Over the years, we have received a great many repeat orders from our clients. We believe demonstrates quite clearly the relationship of both trust and respect that we have with them.

One recent example is a repeat order for the construction of a complete process water and wastewater treatment plant.

This is from a leading PCB manufacturer. The overall plant comprises both an ion exchange deionisation facility and a treatment plant for wastewater of various types.

In addition to the trust that exists between the companies, H+E was able to clearly demonstrate a proven treatment concept that addresses the client’s current and future needs.

The very clear goal of this is to increase the flexibility, cost-effectiveness and availability of the plant. For example, the opportunities for resource recovery have been improved. This therefore reduces operating cost and also reduces the environmental impact of the plant.

Wastewater Treatment Plant for the New Graphene Engineering & Innovation Centre

The pre-assembled and tested plant immediately before delivery to site

H+E has recently delivered a new Wastewater Treatment Plant for the new Graphene Engineering & Innovation Centre. This is for the University of Manchester, where graphene was first isolated in 2004.

Graphene – The Material

Graphene is amazing; dubbed the world’s first 2-D material, it is 200 times stronger than steel, yet incredibly thin and transparent. The potential applications for its use are incredible! There has been more than a decade of research into the vast potential that this incredible material has to be used in our everyday lives. The new GEIC will provide ever better facilities to keep Manchester at the forefront of its development.

Wastewater Treatment

Wastewater collected from the R&D facilities will flow to a network of collection pipes. From there, pumping systems transfer it to the treatment plant.

Due to the potentially enormous variation in incoming quality, three separate tanks collect and treat the wastewater in batches.

Chemical dosing is automatic.  Automatic systems then check that the wastewater is suitable for discharge to foul sewer. There is a possibility of various concentrations of a range of organic materials being present. This is also analysed.

Pre-Assembly & Factory Testing

H+E manufactured, assembled and tested the plant in our factory before delivery. In recent years, H+E has dramatically increased the amount of pre-assembly and factory testing done for its plants. The prime reasons for this are to both improve the quality of equipment supplied and also minimise installation time on site. These continuously-uprated targets are totally in-line with H+E’s philosophy of Continuous Improvement.

Long-Term Support

We always try to keep in regular contact with all our clients. We have some who we still visit regularly, and whose plants are well over 25 years old and working fine! But, even then, when we look back at the systems we supplied just a few years ago, we realise how much the quality of what we supply has improved. This means that our philosophy of Continuous Improvement is important; it really works!

A high percentage of our overall business is from clients placing more orders with us. So, although we know we are a long way from being perfect, we think it is reasonable to assume that we are doing a fairly good job and that our clients are satisfied!
