Hydra Block is an easy to use and cost-effective solid block containing natural bacteria, stimulants and natural growth enhancers for efficient and continuous cleaning of grease traps, pumps , lift stations, sewer lines, wet wells and other waste treatment systems where heavy grease build up is  a problem.

How Does Hydra Block Work:

Hydra Block includes a balanced combination of bacteria, enzymes and nutrients that seeds a new system for a rapid start as well as cleans clogged systems. The product effectively maintains degrading activities inside the septic tanks, grease traps, lift stations etc. and eliminates related problems including FOG deposit, blockages, and malodours. The natural bacteria included in the block feeds upon soaps, grease, proteins, oils, fats and cleaning products. Hydra Block provides continuous action and ensures proper functioning of the waste treatment systems.

How To Use


  • Use 500g to 1kg of Hydra Block to treat a daily flow of 150 cubic metres.
  • For higher flow rates or requirement of extended degradation use multiple blocks, 2x5kg.

Initial treatment:

  • Clean the traps prior to treatment. Use recommended dose of Hydra Block according to effluent inflow.
  • Use double the recommended dosage if precleaning is not done.

Maintenance Treatment:

  • Install a new Hydra Block when the previous one reduces to 50-60% size, to maintain sufficient bacterial activity.

General instructions:

  • Place Hydra Block directly in the area meant to be cleaned.
  • Place the block away from the direct flow of incoming effluent. Keep the block in the area with lesser turbulence of water.
  • Use rope to suspend the Block in such a way that it is always underwater, even when the water level is at the lowest.
  • Ensure that the block does not hinder or entangle with any equipment or lines.

Instructions for use in Lift stations:

  • Use 5 kg of Hydra block for 200-300 cu metre/day of sewage flow. Clean the lift station before treatment. Drop Hydra Bio block into the station in the area with good inflow of water.
  • Ensure Hydra Block does not touch the bottom of the well but remains submerged.
  • Hydra Block dissolves and proper inoculation of bacteria occurs with the low to average water inflow of 20 - 400 cu metre per day.
  • Check block every 2 to 4 weeks.
  • Replace the block after it degrades to its 50% to 60% of the original size.

Instructions for use in Manholes:

  • Suspend Hydra Block in waste stream of the sewer line. Submerge the block completely; making sure that the maximum amount of sewage comes in contact with the block.
  • Secure Hydra Block with the help of a rope so as to keep it from floating down stream.
  • Use 500 grams of Hydra Block for smaller mains or manholes.


Instructions for use in Grease traps:

  • Place 500 grams of Hydra Block in at least two chambers of the grease traps (if possible), at the place where inflow provides turbulence.
  • Secure the rope used for suspending the block firmly.
  • Break the existing grease mat.
  • Clean/pump the grease trap before treatment to get the best result.

Great product

Our small takeaway business needed the grease and fats removing. I received my product very quickly and applied it straight away to my grease trap and has done the job well.

FOG build up
24 June 2018  | 

Our chocolate factory uses a manual grease trap where recently we have had to keep emptying too often. The FOG build up was blocking the system so we came across Hydras Bio Block which we added to our grease trap. Our grease trap no longer has frequent emptying needs.

Wet wells
11 May 2018  | 

We needed a product to help degrade the fats in our wet well, I purchased the 5KG bio block and allowed for it to sit for 2 weeks. When I checked on it again the block was slowly dissolving so I allowed for it to continue doing its work. I could tell it was working due to the system running easier and the odour had dissapeared.
