Situation

A leading waste management and recycling company that specialises in collection, treatment and disposal of hazardous wastes commissioned Kolina to demonstrate the suitability of its patented EC treatment system against injected wastewater from oil drill sites. Adequate reductions in the contaminants of concern will help provide safe discharge of the treated injected water to sea, or possibly reuse. A successful large-scale demonstration would therefore significantly reduce disposal costs, as well as enhancing the green credentials of drilling operations in the UK.

The main targets were to consistently demonstrate high reduction rates in the following to allow for safe discharge to sea or open water bodies:

• Petroleum hydrocarbons
• Dissolved metals
• Chlorides
• Sulphides
• Ammonia
• Total nitrogen

Solution

A demonstration of the EC technology to consistently achieve high reductions of the concerned contaminants. The system was fully automated and required little operator intervention.

Benefits to Client

No chemical input and operator input of just 30 minutes each day. Reduction efficiencies achieved:

• High Reductions

• • Petroleum Hydrocarbons – 99%
  • Dissolved metals – 60%
  • Chlorides – 60%
  • Total Nitrogen – 60%
  • Ammonia – 55%
  • Sulphides – 99%

• Commissioned in 2 weeks
• Targets achieved? – yes!
• Chemical-free solution
• Minimal operator input

Situation

A leading crisp and snack manufacturer was seeking an effluent treatment partner to help deliver cost reductions and achieve discharge consents across 3 manufacturing sites.  Existing treatment plant was no longer fit for purpose, resulting in regular  discharge consent breaches, and group sustainability targets were not being achieved.

The challenge was to deliver an alternative technology to chemical dosing, capture by-products for recycling and re-sale, and ultimately reduce the total cost of operations. Automation was crucial in order to minimise operator input.

Solution

Following a comprehensive feasibility study of all group manufacturing sites, Kolina proposed their proprietary electrocoagulation solution, coupled with a 3rd party pre-treatment plant, to be fitted to the existing waste water treatment process. This was installed to provide robust separation of heavy solids from potatoes within the treatment train. A common approach facilitated the installation of Kolina’s standard electrocoagulation technology and 3rd party pre-treatment plant across all Tayto sites.

Improving solids capture, and the removal of starch increased the value of recovered by-product.  As a result the customer has since been recognised and, shortlisted for a National sustainability award.

Results

Kolina’s electrocoagulation plants are achieving an average 76% COD and 84% TSS reductions across the group, with no breaches of discharge consents.  Trade effluent discharge costs have reduced by 68% providing significant annualised savings.

Situation

A Manchester based, family owned ethnic food producer was regularly exceeding discharge consent limits and absorbing very high operating costs.

On site space was at a premium as was the operational resource needed to manage any new effluent treatment system.

The required solution must significantly improve the company’s environmental performance and at the same time, reduce costs (both operational and mogden formula).

Solution

To collect a suite of technical sampling, and following  full technical analysis, Kolina installed and commissioned their preparatory containerised treatment solution which, was able to meet the required reduction in loadings, reduce operational input thanks to full automation of the control panel and electro cells, and, they were able to site the plant within the factory grounds

Following the firms engineering team completing civil works, Kolina were able to fully commission the new effluent treatment plant in less that 2 weeks.

Results

The site now operates within its set discharge consent limits and is exceeding the company’s environmental and sustainability targets. An average COD reduction of 82% and TSS reduction of 89% resulted in a overall trade effluent discharge saving of 74%

Situation

A leading Yorkshire based gourmet bacon processor has expanded significantly in recent times to a level whereby space within and around the site was at a premium.

With little available space for a new effluent treatment plant on site and,  with ever increasing costs for the discharge of effluent due to frequent breaches of consent limits, the firm enlisted the help of Kolina’s technical team to discuss and explore available solutions.

Solution

Following comprehensive consultation, a regimented suite of sampling, and analysis of all water streams, Kolina’s containerised effluent treatment plant, incorporating its patented electrocoagulation technology was confirmed as the best solution in this instance.

Installed in combination with an external pumping station, balancing and sludge tanks the plant is able to treat 240m3 of effluent per day.

From completion of civil work by the firms dedicated engineering partners, the delivery, installation and commissioning on site was executed within 3 weeks.

Results

Kolina’s electrocoagulation plant achieves an average 72% COD reduction, and 78% TSS reduction, with no breaches of discharge consent.  Trade effluent discharge costs have reduced by 51% giving an annual saving of £135,000.

Situation

A variable effluent composition at the factory of a leading sauce and condiment supplier meant the incumbent solution often failed to achieve discharge consent resulting in high effluent discharge costs.

Company sustainability targets were not being met, therefore a robust and reliable treatment solution was required.

The challenge was to integrate a treatment solution with existing plant, and, with small footprint. Automation was crucial in order to minimise operator input.

Solution

Following detailed effluent stream analysis, Kolina installed and commissioned a containerised treatment solution incorporating patented electrocoagulation technology within the existing treatment train.

Providing the capacity to treat 240m3 per day, the plant was fully automated in order to manage the variable effluent streams, and minimise operator input in the process.

From completion of 3rd party civil work to redirect the discharge outlet, Kolina’s delivery and integration team installed and fully commissioned the plant in 3 weeks.

Results

Kolina’s electrocoagulation treatment plant achieves an average reduction of 78% COD, and 88% TSS plus, there are now no breaches in discharge consent. Trade effluent discharge costs have reduced by 72%, providing an annual saving of c£115,000.

Situation

A key supplier of pies & baked products to leading supermarkets was failing to achieve strict consent limits which resulted in high effluent discharge costs.

An environmental improvement program was implemented to manage effluent and operating costs in a more holistic manner, in line with their customers sustainability program.

With no current treatment of effluent and limited space available, a rapidly deployed, chemical free, reliable containerised solution was required.

Solution

Following Kolina’s feasibility survey which includes a comprehensive sampling regime, Kolina’s preparatory  electrocoagulation system was selected as the preferred technology.

The containerised plant was sited in combination with external pumping station, balancing and sludge tanks and is able to treat 240m3 of effluent per day without the use of costly chemicals.

Kolina provided full onsite training, and offer a full service and maintenance contract to help manage and maintain the treatment plant. From completion of site deployed civil work, delivery, installation and commission was executed within 2 weeks.

Results

Kolina’s electrocoagulation treatment solution achieves an average 75% reduction in COD, and 78% in TSS. There are now no breaches in discharge consent limits.  Effluent discharge costs have reduced by 68% with an annual saving to the business  of £156,000.
