LEACHATE TREATMENT

Brackish Water Reverse Osmosis (BWRO), Sea Water Reverse Osmosis (SWRO)

Infrastructure

Regional NSW

BACKGROUND

Construction and demolition waste streams from infrastructure and urban development are disposed in dedicated Construction and Demolition (C&D) landfill, separate to putrescible waste from households. Landfills produce leachate that will exceed environmental discharge limits imposed by the local environmental authorities, if not treated to remove contaminants.

Through routine sampling and monitoring, a regional NSW landfill operator identified bromine levels that exceeded their discharge limits. MAK Water was approached to work in collaboration with the onsite wastewater treatment team to provide a rapid solution to limit bromine concentration to below discharge limits in the treated leachate and reduce the volume of waste that had to be trucked off-site for disposal.

SOLUTION

Rental Brackish Water Reverse Osmosis (BWRO) plants were used as the final polishing stage to reject bromine following extensive pretreatment upstream. A Sea Water Reverse Osmosis (SWRO) plant was used to concentrate all the reject brine streams, further reducing disposal costs.
