The Cobra Bio Block® is a biodegradable biopolymer in cylindrical form, containing 9 different strains of bacteria, selected for its fat-degrading properties, and kept within a porous durable net. Cobra Bio Blocks® contain environmentally friendly, safe and naturally occurring micro-organisms and enzymes, which break down Fat, Oil and Grease (FOG) and other organic contaminants.
The Cobra Bio Block® has been developed to prevent the accumulation of Fat, Oil and Grease (FOG), in pumping stations, sewage pumping stations, wet-well tanks and manholes. Suspended in chambers with either chain or rope. Cobra Bio Blocks® are produced in several sizes, ensuring the appropriate size is available for different wastewater flow rates.
– No need for large storage tanks
– Simple to install and operate
– Immediate impact upon application
– Suitable for use across a wide range of environments
– Organic and economical solution
The problems associated with fat and grease build-up in Waste-Water Treatment Plants are well documented. The costs associated with the removal and disposal of fog, coupled with the repair and maintenance costs because of clogging and damaged to pipework and pumps make the problem one worth addressing.
The Cobra Bio Block® has been developed to address the above mentioned problems. The Cobra Bio Block® offers 24/7 operation with no need for dosing equipment, power, or storage and operation space. The block hangs in a wet well, positioned to the in-coming waste water flow. The turbulence of this water slowly erodes the block dosing the complete system and colonising all aspects of the operation.
An initial shock dose of a specialist agent is applied at the earliest possible stage of the treatment. Then the Bio-block is suspended in the primary wet well and passive dosing commences. Though the active ingredients of the Bio Block® are effective immediately, its full effects are not seen for three to four weeks. This is due to the bacteria having to colonise, proliferate and penetrate the fat build-up.
“The trial of the dosing blocks in York has been very successful. The blocks have helped reduce incidents of fat, oils and grease causing blockages in the network and clogging up the pipes under the city to zero. In the last 12 months, we’ve had no pollution incidents linked to fats, oils and grease and no sewage escapes due to fat blockages.”

“The thing that’s great about this product is that they’re easy to install, easy to replace. And they don’t just break down fat that is there, they can also prevent it’s build up as well, so it’s a really cost effective, practical, sustainable solution.”
“The difference is incredibly noticeable if you look at the CCTV footage of the cameras down the sewer network, historically you would come back here to do an inspection and you’d see a coating round the pipe and it really starting to layer up, and the difference it has made is phenomenal.”
