Sewage water on the settlements and on industrical sites produce considerable smell due to high organic matters therein and because of other components. The smell effects should be taken into consideration in the course of sewage collection, disposal, storage, purification and sewage sludge.

For control and disposal of smell wide-ranging products and tailor-made solutions are offered to our Customers by our Company - Professional Média Ltd.

- In case of long sewage conduit of small fall, following connection of pressure pripe, and in case of sewage lifting shaft the smell arising from the sewage in a state of decomposition usually is aired through openings.

- In the majority of cases there is an attempt to prevent the smell in the calm weather by sealing manhole cover, however dangerous gases will be developed by this method.

- Efficient solutions are offered for treatment of air coming from the conduit instead of sealing the manhole cover.
(passive deodorization) Depending on the circumstances the problem can be treated at conduit manhole or on the branch conduit.

- If other openings of the manhole can not be sealed and the gravity conduit leading to pumping station produce considerable smell the only efficient solution can be ventilating the lifting manhole. (active deodorization).

By ventilating the conduit in such a way the enrichment of toxic gases causing corrosion can be prevented as well.

- It is widely known that refuse on the grating is an intensive source of smell, and we have suitable product for neutralisation of the smell as well.

- Treatment of the intensive smell effect in relation to large lifting pump stations of Engineering Structures, presettlements, tanks, lakes and other open water surface (lagoons in food and sugar industry, ventilating tanks and reservoirs of household of waste disposal is successfully solved by our product Lagun' Air C procedure.

The hydrophobic effectice substance sprayed into the water forms film and on the surface of water and has the required effect by evaporation.

This procedure can be used efficiently especially against sulphuric smell and can be prevented in the weather free from wind (at down and inverse atmospheric conditions) that has an influence on the remote environment as well.

Control and disposal of air in the sludge treatment plant, sewage receiver and other smelly places reduces to large extent the need of air exchange and the heating cost in winter time by application of special gel. In interior rooms of buildings for compost pile the intensive smells releasing in the course of zymotic and decomposition can be treated efficiently as well.

By way of treatment considerable reduction in smell can be reached
(70-85 %) on one hand and the working conditions will impove as a result of lower vapour content on other hand, and corrosion will reduce in buildings.

We are able to offer a practical solution for treatment of foul smell spreading in the course of fermentation.

Our product can reduce the strong smell of hydrogen sulphide and mercaptan before adding the structuring and loosening materials (straw, sawdust) to the sludge.

Our product is to be spread on the surface of the sewage sludge neutralizes the foul smell already on the first occassion upto the drying up.

In case of reuse sewage sludge on industrial sites and on settlements the granules to be mixed to the composted sludge will prevent the smell spreading on the environment during the whole period of the decomposition.

Efficiency of traditional and of organic biofilters fillings can be increased considerably by our procedure of Biothys, which the combinated application of the product by the filling of biofilter.

This procedure is especially effective for treatment of sulphuric (mercaptans, H2S), and gases containing nitrogen and fatty acids.
The mixed granules or just spread on the filling once ensures very effective deodorization due to effective agent evaporating evenly.

The product can be combined with any kind of organic filling used in the usual biofilters or other units (cortex in pieces, root, sawdust), peat or with filling of mineral material (zeolit).

This procedure can be applied on a simple way, by little cost and no need reconstructuring the existing unit.

- When cleaning up contaminated inner and outer claddings (e.g.: stare cases, passages, dining rooms, warehouses, storage rooms for dust bins, etc.) remaining smells can often not be fully disposed and killed even by using strong oxidants. Using our mop-up fluid, this problem can be solved with guaranted results and cost-effectively due to the high extent of dilution.

Our mopping up liquid can be combined with disinfectants.

- Our concentrated agent can effectively be used for smell disposal in waste water drain pipe mains, gulleys of bathrooms, channel systems which can directly be used for smell disposal at the smell sources or in not accessible places such as pipeline systems, channel mains by treating the media flowing therein.

- When sprayed onto walls and skirting boards, our special ? highly effective smell killer liquid having remaining effect is excellently suitable for treatment ? disposal of smells, etc. produced in the processes of decay and/or combustion of e. g. organic substances and hydro-carbons, animal and vegetable fats as well as following water flooding ? fire extinguishing.
