Soil cleaning technology
Valena produces concentrates of Humic acids in the form of thick paste in 1, 20, 200 liter containers using patented unique technology. We supply the following products and solutions for the use of humic acids:
- Potassium humate (sodium humate, depending on the purpose) - humic fertilizer made of peat;
- Humic concentrate of brown coal for treatment, mud baths, cosmetics and applications;
- Humic concentrates for cleaning soil from contamination with oil products and heavy metals.
Humates are not toxic, not carcinogenic, not mutagens, not teratogenic.
Humic acids made from brown coal have an advantage over other mud preparations in the following properties:
- no harmful organic and inorganic compounds;
- there is no unpleasant smell;
- can be used not only in specialized clinics;
- aesthetically convenient;
- the possibility of using in small volumes.
