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.

Vegetable wash water disinfection

Biochemica UK Ltd has been awarded the supply contract for wash water disinfection at a leading Lincolnshire vegetable factory. In addition to Biochemica’s on site involvement with wastewater treatment, training and consultancy this move increases our technical input and product supply to cover factory disinfection technologies. This completes the final stage in on site total water management. Future design and engineering projects between the two parties are planned for 2008.

Influent to effluent – the complete package

Biochemica UK Ltd treats influent to effluent as part of an innovative approach to Total Water Management at a leading food processor in East Anglia. Biochemica have expanded their site presence from wastewater to factory and process cooling water treatment, as well as providing additional outsourced engineering services. Water used as part of the production process must be of a high standard and therefore requires pre-treatment, as does the water used in the cooling systems on site. As shown through our initial involvement with wastewater treatment, our high level of technical knowledge and service is applicable for all aspects of water treatment on site. “We are very pleased to have been awarded total site management regarding water treatment” said Dave Ruddy of Biochemica, “We look forward to working with our client on current site projects as well as future plans involving outsourced process design and engineering work through Biochemica.”

Biochemica launch new website

Biochemica UK Ltd launched their new web site on 1st September 2007, detailing their complete solutions approach to industrial water management and associated environmental services. Commenting on the new site Dave Ruddy, a Director of Biochemica UK Ltd added, “Biochemica are involved in all aspects of industrial water treatment across a diverse range of industries. The aim of the new web site is to allow browsers to see our core areas of involvement and services provided.

“The site illustrates that Biochemica have the capabilities to provide the most effective solution to best achieve clients’ expectations.”

Trial success

A successful full scale plant trial has been completed by Biochemica UK Ltd at a tannery in East Anglia. Following a site survey, test work and consultation with plant engineers a full scale trial was implemented using a different treatment chemistry. In addition some process changes were also put in place with a view to further enhancing performance. During the trial a consistent improvement in DAF COD and TSS reductions were recorded. The chemical requirements for the process were also less than before thereby reducing plant running costs. These changes have now been implemented on a permanent basis.
