CP 1100 - Odours / Sulphides (h2s) Biological Oxidation Powder

Biological oxidation of Sulphides to produce harmless, odourless end products.

Sulphides develop in wastewaters from the anaerobic decomposition of organic matter containing sulphur or from the reduction of sulphites and sulphates. The most common sulphide encountered is hydrogen sulphide (H2S). This is a colourless, inflammable gas with the characteristic odour of rotten eggs - a foul smell.

Odour control is a major concern in the operation of many municipal and industrial wastewater treatment plants. Foul odours are a public nuisance and give rise to unfavourable publicity. Environmental legislation is becoming stricter all the time especially in relation to odours / air emissions released adjacent to sensitive areas such as housing, recreation parks, schools, etc.

The blackening of wastewater and sludge usually results from the formation of H2S which in turn combines with the iron present to produce ferrous sulphide - which produces a noxious odour when disturbed e.g. when pumping wastewater from storage lagoons or when wasting and thickening sludge.

H2S released to the atmosphere above the wastewater in sewers not flowing to full capacity tends to accumulate at the crown of the pipe. H2S can be oxidised to produce sulphuric acid that will attack both cast-iron and concrete sewage pipes - this corrosion can be severe enough to cause collapse.

H2S is toxic to nitrifying bacteria. These bacteria are highly sensitive and if H2S is present even at low concentrations the nitrifying biomass can be wiped out. The result is lost nitrification, increased levels of ammonia in the final effluent, possibility of fish kills if final effluent is discharged to a sensitive river as well as heavy fines if discharge license is exceeded.

Build-up and accumulation of H2S in enclosed areas such as pump sumps can be detrimental to the health of the operator. In many pump sumps the operator has to descend a ladder to check or repair a float, etc. If gas has accumulated in this area then the health and safety of the operator is compromised.

CP 1100 is a biological product that has capabilities of oxidising H2S and other reduced sulphur compounds to produce non-harmful, non-corrosive, odourless end products.

Typical situations in which the use of CP 1100 is beneficial include: -

  • Treatment of odours associated with primary and secondary sludges
  • Removal of H2S associated with storage of wastewater for long periods of time
  • Removal of toxicity in wastewaters associated with nitrification
  • Seeding or reseeding of biological gas scrubbers / biofilters
  • Prevention of build-up and accumulation of H2S gas in enclosed spaces.

CP 1100 uses only harmless, natural micro-organisms that eliminate the problem by oxidising soluble sulphides in a highly effective and environmentally acceptable manner.

What is CP 1100?

CP 1100 is a biological product specially formulated to provide chemolithotrophic microbial strains that effectively oxidise H2S and other reduced sulphur compounds to ultimately produce sulphate.

The microbial species in CP 1100 grow slowly so it is important to add sufficient numbers so that an effective population is generated as fast as possible. Regular maintenance dosing will sustain biomass and performance.

The types of systems in which CP 1100 can be used include: -

  • Biological gas scrubber / Biofilter
  • Pump sump
  • Sewerage pipe network
  • Storage lagoon
  • Anoxic tank
  • Primary sedimentation tank
  • Picket fence thickener
  • Thickened sludge storage tank
  • Sludge press / Belt press

CP 1100 can be used with other CP 1070 series products to address additional problems in a system.

Directions for use

CP 1100 is supplied as a powder product on a cereal base and must be rehydrated before use. This is achieved by adding the required quantity of product to lukewarm (~30oC) water in a suitable container. Apply 1 part product to 10 parts water, stir well and allow to stand for 1 hour before application.

As each application is unique and has different characteristics it is important to assess the site before deciding on a dosing programme. The Technical Department will provide assistance in the assessment of the site, designing a treatment programme and recommending a suitable dose point.
