WCS Environmental Engineering (WCSEE) technology has been selected to deliver wastewater treatment at a landmark industrial development in east London, UK.
WCSEE will deliver a full treatment system, with primary, second and tertiary stages, to manage wastewater produced by up to 1,380 workers each day. The below-ground system will comprise a primary settlement tank, a hybrid-submerged aerated filter (SAF) – unit to provide secondary biological treatment and a sand filter to remove any excess suspended solids from the treated wastewater before it is discharged.
The system has been designed to treat flows to tight environmental standards of 10mg/L biological oxygen demand (BOD), 15mg/L suspended solids, and 3mg/L ammonia. As such, the sand filter will provide a level of tertiary treatment to bring consent standards above what is normally expected from a biological process.
Momentum is a logistics scheme transforming a 20-acre brownfield site next to the River Thames in Rainham. Being delivered by HBD and Barings in a joint venture partnership, Momentum will comprise four units and is designed to be a ‘carbon neutral, sustainable space that meets occupiers’ responsible business and environmental, social and governance obligations.
WCSEE technical manager Dominic Hamblin said, “Our modular treatment units are built off-site and can be easily transported. The technology has a 30% smaller footprint than comparable technologies and their compact design enables units to be installed in locations where space is at a premium, such as a busy commercial site.
“Our HiPAF-SAF range meets EU environmental discharge consent standards without the use of chemicals, and has the benefit of a built-in timer for the blowers, which can halve the amount of energy used to treat effluent. The technology is regularly specified by UK water utilities and is a choice for sensitive locations.”
