Summary

Bacterial product “Ecobel” is a highly effective product used for soil and water purification from oil and its recycle products. The product consists of extremly active micro organisms-decomposers of oil that use it as a source of energy
The product guarantees liquidation of oil contaminations of soil and water over a period of 4 months during spring and summer.

Description

Bacterial product “Ecobel” is a highly effective microbial product that can activate the process of degradation of spilled oil over soil and water surface. The product’s efficacy is based on the ability of strains of micro organisms-decomposers to use carbon of oil hydrocarbons as the only source of energy. Treatment of oil contaminated soil with bacterial product “Ecobel” consisting of dry biomass of micro organisms-decomposers includes the following stages:


Suspension from dried forms of “Ecobel” product in field environment is prepared with the help of standard machines for drive fluid preparation of APT “Temp” type. Steeping of biomass in water shall last at least for ½ hour. For steeping of 100 kg of the product 1000 l of water is needed.
The suspension is sprayed on the soil surface with backpack sprayers ORP-G, ORD-B or with mounted sprayers aggregated on tractors of ON-10 type depending on the contaminated area.
Water surface contaminated with oil is treated by means of “Ecobel” product being sprayed with the help of mesh sieve for small areas and with the help of mechanical sprayer for larger areas. These procedures shall be performed on a regular basis depending on oil film accumulation

Technology type

Technical advantages and economic benefits

The product is meant for treatment of soil with contamination level of up to 10 kg/m2. The amount of product being used is 25 g per 1 kg of oil. Calculation of product consumption rate for water treatment is based on the oil:product rate which is equal to 1:0.1. If 1000m2 of water contains 100 kg of oil, then 10 kg of “Ecobel” product is needed for bacterial decomposition. The product ensures liquidation of oil contaminations of soil and water over a period of 4 months during spring and summer. Benefits of using “Ecobel” bacterial product for purifying of water and soil from oil and its recycle products over other physical-chemical methods consist in its cost effectiveness:
