Case Study
Hampshire Cosmetics Ltd, a toiletries and cosmetics manufacturer based in Waterlooville, has significantly reduced their trade effluent bill with the help of WPL Ltd’s new approach.

The Scope:
In 2008 WPL Ltd approached the company with an innovative method of significantly reducing trade effluent bills and the environmental impact of discharging trade effluent from its manufacturing plant in Waterlooville Hampshire.

During 2008 an estimated 45 m3 of effluent per day was produced, and based on Mogden Formula calculations their trade effluent bill was running at nearly £10,000 per month, with COD’s (chemical Oxygen Demand) at 8,500 mg/l and s.s. (suspended solids) at around 800 mg/l.  The bulk of the effluent is produced during the washing of the blending vessels and contain a wide range of residue from products such as creams and shampoos.

With potential annual increases on the horizon, Hampshire Cosmetics realised their long term bills were likely to double within 5 years, significantly out stripping the rate of inflation and seriously impacting on overhead costs.

The Solutions
In initial talks with WPL Ltd, the company was proposing to install a full sized treatment plant on site and remove the resulting sludge by tanker.   However, during this period WPL Ltd undertook site trial work, identifying a chemical regime that would reduce the COD to less than 2,000 mg/l, however this would increase s.s. and generate solids that would require removal.

With further works and discussions with Southern Water it was agreed that if the COD could be reduced, the resulting s.s. could continue to discharge to sewer negating the need for using expensive sludge removal techniques. The advantage to Southern Water is the COD is converted to solids and can be removed at the primary settlement stage in the treatment works, helping to reduce loading on the biological phase of treatment.

WPL Ltd has won the 5 year contract to supply capital equipment, service and chemicals for a monthly fee.  With the new treatment process in place to reduce the COD the charges from Southern Water have come down significantly.  Combined, these costs give the client an immediate saving of £1,750.00 on their previous monthly outgoings and effectively provide a buffer against any future increase in charges.

Summary
WPL has over 20 years experience in effluent treatment, with a wide range of internal skills and an extensive service team we offer continued development and support to all our customers.  As well as the already experienced cost savings and convenience of the WPL contract hire option, Hampshire Cosmetics will see additional long term benefits too, as WPL will continue to install equipment allowing continued development to meet either stricter future consent standards or to further reduce costs.

WPL provides innovative and reliable wastewater treatment, rainwater harvesting and grease management systems for domestic, commercial and industrial markets as well as holding a prominent position as a supplier to the water utilities.  As an internationally recognised leader in the design, manufacture and supply of both standardised and bespoke environmental solutions, WPL Ltd is dedicated to ensure the provision of high quality products and services.
