In the wine producing industry, efficiently maintaining the waste water treatment plant is a focal point; protecting the environment, avoiding to cause pollution which leads to criminal and administrative penalties and allowing the purified waste water to flow in the public sewage system.
Purifiers are usually built in reinforced concrete, performing their duty by mechanically separating the elements in the waste water.
Considering the material used for building and the PH of the waste water, deterioration of the structure and of it's performance is inevitable.
Reinforced concrete when in contact with the PH of the waste waters, 12,5/13 basic, starts a carbonization process that results in it no longer being waterproof or properly sealed.
The waste waters that come from producing wine are mainly either extremely acid or extremely basic that compromise the purifier's integrity and functionality.
The damage is initially on the surface and eventually, through cracks and fissures, penetrates to the core.
The degradation process Is accelerated whenever reinforced concrete is directly in contact with sulfates, chlorides or alkaline products, the very chemical elements found in the wine industry waste waters.
The salt content, abrupt variation of PH, chloride concentration, surfactant sulfates are the main factors we consider because they are the elements which impact the most the degradation process of the purifier.
For the waste waters to be channeled in the public sewage system they must follow specific guidelines:
- PH between 5,5 and 9,5
- Chlorides max 1200mg/L
- Sulfites max 1mg/L
- Surfactants max 2mg/L
Water samples taken from wine production waste waters show PH intervals between 4 and 11 which are obviously out of the acceptable range and must be purified. It's fundamental, both for the environment and to avoid criminal and administrative sanctions, that these waters do not disperse because of the degradation of the concrete present in the purifying system.
D5 Italia has analyzed the problem carefully, trying to find a solution which is cost-efficient and effective in maintaining the normal functionality of the purifiers, protecting the wineries form sanctions derived from improper management of waste waters and avoiding invasive jobs like removing the old purifier and building a new one.
D5 Italia has developed D5003, a polyurea equipped with every certification specifically designed to withstand PH variations between 4 and 11; can be sprayed using D5 Italia machines.
D5003 Polyurea has both a preemptive action and a decisive action when applied. The research D5 Italia has done to come up with the formula for D5003 Polyurea is specifically tailored for the problematics that are encountered in purifying systems and in other systems which share abrupt and aggressive PH variations.
D5003 Polyurea, when applied continuously, allows the formation of a protective coating on the concrete surface of the purifier, stopping the degradation process caused by the chemicals found in the waste waters and protecting the whole system.
D5003 Polyurea can be applied using Bi-Mix D5 Italia spraying machines to guarantee a perfect job.
D5003 Polyurea forms a perfect waterproof coating on the surface on which it's applied, adhering completely and following it's thermal variation, therefore avoiding the formation of cracks or fissures.
D5003 Polyurea has a very quick reticulation of 3/5sec. This allows it to be quickly installed and ready for use, allowing the user to be able to not lose any kind of productivity as is customary because of the longer time others resins take to be work-ready.
D5003 Polyurea, when applied using D5 Italia spraying machines allows for:
Better maintenance and cleaning of purifiers - The ceramization of the walls by using D5003 Polyurea allows any solid waste in the waste waters to slide off.
Less operational costs - A purifier which has been treated with D5003 Polyurea can be quickly refurbished in much less time and much more cost-efficiently than a maintenance job on concrete.
D5003 Polyurea is the ideal solution for and winery interested in maintaining the purifier's functions efficiently and for long periods of time.
