New Industrial Wastewater Treatment Plant

H+E is currently designing a new plant to ensure that the client’s effluent is discharged well within the Consented limits. We know very well that maintaining production is the most important factor; the treatment plant is simply providing a service.

The plant will be designed to handle up to 20m3/h of incoming wastewater, which is a relatively common flow rate required for many companies. This is the second one of this size that we are currently designing.

Designing for the future

For us, it is very important to know both what our clients’ needs are and also how those needs might change in the future. The required quality of treated effluent discharged has become much more stringent over the years because of increased environmental concerns. BAT (Best Available Technique) is now a very important part of designing plants. Water must be used efficiently to produce less effluent. The possibility of recycling treated effluent is a more important consideration. So, all the plants we design and install take such needs into account, not necessarily by adding in all options now, but by ensuring that they can easily be added in the future.

Long-term support

H+E has designed, manufactured and installed such plants for many years. Our roots do actually go back to 1896! We always have at the top of our “wish list” that every single client of ours must be satisfied with what we provide. So, we make sure that the treated wastewater meets the necessary quality requirements and  at a reasonable cost. The plant will do this job both efficiently and for many years.

As a matter of course, we offer long-term Service visits and Technical Support to every client. You decide whether you accept this or not and how often you would like them. We do have many clients who do so and, what’s more, many plants which are still working well after 25 years and more. We are currently in discussions with one long-term client to upgrade a plant that was installed in the early 1990s. It is still working fine, although it now needs a bit of “TLC”!

Our wish is to maintain long-term contact with every client.

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.
