Treatment or handling of black and grey water on board ships is becoming increasingly necessary as the requirements of MARPOL Annex IV have come into force, and this area is also constantly being revised. All ships have to have some facilities to handle sewage, and we offer biological products to keep these performing at optimum levels. Even something as innocuous as a locally sourced chemical toilet cleaner can have a negative effect on the sewage plant, and we offer multi-purpose alternatives that can clean toilets, have a positive effect on scale in the pipework and augment the sewage treatment process. Collection of black and grey water also generates specific problems such as blockages, odours and corrosion, and we have problem solving products targeted at these areas.
