Platinum Samandy Ventures Limited in conjunction with SHEQPLUS, as an expert in Bioremediation, who has successfully project managed large sites requiring restoration and rehabilitation. Utilising a patented product and technical expertise, SHEQPlus™ provides a turnkey service. SHEQPlus™ can also provide Environmental Impact Assessments (EIA) and Environmental Management Plans (EMP) compliance. 

We specialise in Bioremediation of contaminated soil and wastewater as well as closure and rehabilitation plans. SHEQPlus™ is a founder and partner in a Compliance Management System known as ELINT Smart Software-Keeping You Compliant. Let SHEQPlus™ show you how www.elint.co.za will ensure you have total onsite Compliance and Project Management during your bioremediation project.

Methodology

The Bioremediation process was explained as follows:

  • Establish the source / sources of contamination.
  • Dig a trench, lay bidim in trench, place a French drain system inside bidim as follows:
    • Lay a layer of washed stone inside bidim.
    • Place Cordrain pipe on stone.
    • Place feed drip pipe with pressure release valves inside Cordrain pipe.
    • Cover Cordrain pipe with stone.
    • Close bidim over stone.
  • Mix an absorbent, SpillSorb, into and onto the top of the drain system as an absorber of hydrocarbons.
  • Add hay to assist in supplying oxygen and Biodegradation.
  • The trenches with Cordrain pipes must be dosed with microbes (imported from the UK) that secrete enzymes and multiply asexually on a regular basis. This will result in millions of microbes / enzymes eating up the Hydrocarbons. More microbes / enzymes nutrients, chelating agents, surfactants and oxi- release nutrients must be fed on a regular basis via the drip pressure pipe.
  • All trenches must be layered with SpillSorb will absorb and encapsulate the Hydrocarbons. This will create a biomass in which the microbes / enzymes will live in and carry on multiplying until the food source (i.e. Hydrocarbons) are depleted.
  • Palm trees must be protected by removing most of the polluted soil and by placing a protective layer of SpillSorb around and under the tree to prevent polluted water from getting to the roots.
  • All the Cordrain pipes must flow to a central point where (3) interceptors / oil traps must be placed. These will be the same as used in any garage or wash bay. They will separate the petrol and diesel from the water and the clean water will flow into a 3600 litre holding tank.
  • The entire system must be on a timer and will circulate creating even distribution of microbes / nutrients etc. plus via circulation increase the oxygen / air supply, thereby enhancing the bioremediation / degrading process. The 3600 litre holding tank is to have a pressure switch which will bleed off automatically and discharge the clean water via pressure through a SpillSorb filter. The filter will remove any traces of Hydrocarbon and any heavy metals.
  • The clean water will then discharge into the sewer.
