Wastewater contract

Biochemica UK Ltd has won a new contract to treat and manage the effluent treatment at a leading vegetable processor based in East Anglia.

The current treatment process was examined in terms of removal efficiencies for COD. Under the previous approach there was a minimal reduction in COD. After a preliminary study a different approach was applied to the treatment philosophy with COD reduction subsequently improved by over 50%. Additonal benefits were also seen in pH control through the new Biochemica treatment programme.

Biochemica secures steel contract

Biochemica has won a new contract to manage the water treatment at a leading North East steel plant.

Dave Ruddy of Biochemica commented: “Biochemica is delighted to have been awarded this contract. It illustrates the wide coverage of industries we serve in the region. We hope to offer additional services in addition to water treatment by assissting in other engineering and environmental projects.”

Multi site deal

Biochemica has been successful in its bid to extend its services to manage water treatment for a global packaging company across multiple sites.

Dave Ruddy said: “Biochemica has a long and established relationship with our client in the area of water treatment, as well as other environmental projects, so this additional contract extends our remit within the group.

Biochemica has water treatment contract extended by vegetable producer

Biochemica has been awarded a two year extension to its current contract to provide water treatment services and products to a leading vegetable producer based in East Anglia.

The client’s Engineering Manager commented: “After a very productive and successful first year with Biochemica it was a unanimous decision to further extend the contract for another two years. Their technical knowledge and input into our company has helped us improve the efficiency of our plant and their diversity has enabled us to get a big project underway which will further improve the efficiency of our entire site. The standard of service, delivery times and willingness to help with absolutely anything were also key factors as to why it was an easy decision to keep Biochemica on board.”

Biochemica increases presence in North East

Biochemica has increased its presence in the North East with the addition of another office in order to meet demand for its specialist water treatment services within the heavy industrial Teesside area.

Dave Ruddy, a director of Biochemica said: “The new premises allows Biochemica to be close to our customers in the Teesside area as well as becoming the main office for business in the North of the UK. The excellent facilities at the new location will help Biochemica interface more efficiently and to an even higher standard with our ever expanding customer base.”

Tim Robinson of Biochemica to have research published

A research paper entitled ‘Remediation of Textile Dye Waste Water Using a White-Rot Fungus Bjerkandera adusta Through Solid-state Fermentation (SSF)’ by Dr Tim Robinson of Biochemica UK Ltd and Dr Poonam Nigam of the University of Ulster will be published in a forthcoming edition of the journal Applied Biochemistry and Biotechnology.

Dr Robinson has a background in textile dye removal research and has previously developed a novel two stage approach for the removal and remediation of textile dyes from waste water. Other publications include topics covering fermentation technology, effluent treatment and odour control.

Biochemica awarded multi site pharma deal

Biochemica UK Ltd has agreed a multi site deal with a leading pharmaceutical group to provide complete water treatment and solutions to its UK sites.

Phase one began in June with the remaining sites falling under the remit of Biochemica before the end of 2008 as part of the strategic handover.

Successful full scale trial of new cooling tower cleaning technology

Biochemica UK Ltd has successfully completed a full scale site trial of a new foam technology designed for cooling tower cleans. This novel approach does not require packing to be removed as per conventional cleans. Figure 1 below shows a schematic correlating to the areas shown after endoscope inspection in Figures 2 and 3. Figure 2 shows the endoscope results prior to cleaning and highlighted moderate scale and biofilm formation.

Scale deposits were also found to be concentrated towards the centre of the pack. Figure 3 illustrates the effect of cleaning after the foam application. It can be seen that a significant improvement in biofilm and scaling was achieved on all sections.

Biochemica brings plant back to life through phosphate removal

A plant suffering from ongoing performance issues regarding phosphate removal from its effluent stream approached Biochemica to help rectify the situation. The consent to discharge for phosphate was 15mg/l, which the plant had achieved just once over the prior 12 months.

Biochemica quickly performed test work to optimise chemical dose rates and illustrate the expected phosphate removals that could be realised under the new treatment regime.

Vegetables… water… and Biochemica!

Biochemica has teamed up with some of the leading vegetable producers and processors throughout the UK to help reduce their water costs.

Cost savings in terms of cleaner water for discharge, and where possible, reusing this treated water back into the process has made the Biochemica total water management appoach appealing to many firms within the food industry.

Irish contracts

A contract to provide treatment chemicals and technical service has been won by Biochemica at a pharmacetical plant in Ireland. Work will initially concentrate on the treatment and management of the boiler/cooling water systems with engineering projects involving wastewater process design also underway.

Biochemica has been awarded a contract to provide consultancy and engineering services at an industrial effluent plant in Ireland. Biochemica will provide consultancy on process and chemical engineering aspects as well as plant and instrumentation maintenance.

Contract award

Biochemica UK Ltd have been awarded a contract to supply products and provide on going technical service for an effluent treatment plant at a leading multi-national packaging company.

Performance issues had been reported with the centrifuge used for liquid/solids seperation. As with most projects, small scale test work was initially carried out to understand the chemistry of the process. Following on from this, a full scale trial was implented under the new process changes and chemical treatment programme, producing much improved dry solids and a clearer centrate. Improved dewatering had a beneficial impact on solids disposal; more solids and less water was transported off site for treatment, improving the cost of disposal per tonne of product.

Cost savings

Biochemica UK Ltd has successfully completed a 12 month, full scale trial at a multi-national pharmaceutical plant to investigate high running costs and inconsistent performance of their previous cooling tower biocide programme.

After fully understanding the previous chemical approach, and more importantly the areas for improvement, our treatment regime was implemented, initially on an isolated cooling tower. Results from this study showed that the Biochemica treatment chemistry was more effective than the previous technology, so the remainder of the on-site cooling towers were brought on line under the new regime.

Scottish success

Biochemica were consulted regarding performance issues in a dissolved air flotation (DAF) unit at a wood panel producing factory in Scotland. After initial test work to evaluate an alternative approach to the previous treatment technology, a full scale trial was commissioned.

By implementing the Biochemica treatment chemistry some process changes were required… for the good! This resulted in a simpler, more effective and more cost efficient process. Enhanced liquid/solids separation was achieved over the trial period with solids removal and COD reduction much improved over the previous set-up. An initial COD of 334,000mg/l and 3,200mg/l of TSS was reported prior to treatment. The final discharge COD and TSS was 1,250mg/l and 28mg/l, respectively.
