Filter za Gvožđe i Mangan - Deferizator vode

Deferizatori su uređaji za uklanjanje rastvorenog gvožđa i mangana iz vode, koji u većim količinama mogu vrlo negativno uticati na mnoge tehnološke procese ili učiniti vodu vrlo neprijatnom za piće. Deferizatori su punjeni specijalnom katalitičko-filterskom ispunom koja katalitički oksidiše rastvoreno gvožđe i mangan u nerastvornu formu njihovih hidroksida i jednostavno ih otfiltrira na sebi. Po zasićenju automatski se pokreće KONTRAISPIRANjE - BACKWASH koje izbacije naslage u ODVOD. Nakon decenije isprobavanja različitih katalitičkih ispuna renomiranih svetskih proizvođača Hydrolux Project Team se opredelio za NAJBOLjU OPCIJU - KATALOX LITE Nemačkog proizvođača WATCH WATER.

 

Revolucionarna tehnologija - KATALOX LITE!

Kod većine katalitičkih ispuna starije generacije problem nastaje zbog nedovoljne količine rastvorenog kiseonika u vodi. Ukoliko voda sadrži dovoljnu količinu rastvorenog kiseonika, svi deferizatori jednostavno filtriraju zagađenu vodi odnosno iz nje uklanjaju gvožđe i mangan. Ukoliko voda ne sadrži dovoljno rastvorenog kiseonika (što je obično slučaj kod voda iz dubokih bunara) nastaje problem; jedna opcija je da se dodaje neko oksidaciono sredstvo kao što je npr. kalijum-permanganat ili neki oblik hlora. Sredstvo se dodaje odgovarajućom dozir pumpom spregnutom sa meračem protoka kako bi se održala ista koncentracija bez obzira na promene protoka ŠTO ZNAČAJNO PODIŽE CENU OPREME. Drugi način je da se periodično vrši regeneracija katalitičko filterske ispune propuštanjem nekog oksidacionog sredstva, što se svodi na SLIČNO ILI ISTO.

Drugi, možda mnogo teži problem je u tome što se deferizacija vode svodi na KONTRAISPIRANjE - BACKWASH. Deferizatori su glomazni uređaji koji za otklanjanje Gvožda i Mangana u konfiguracijama srednjeg ili većeg kapaciteta ZAHTEVAJU VELIKU KOLIČINU VODE za kontrispiranje. U praksi je često slučaj da uređaj koji je u stanju da isfiltrira npr. 3m3/h zahteva KONTRAISPIRANjE od oko 5m3/h ŠTO JE SKORO DUPLO VIŠE OD ZADATOG KAPACITETA. Ovaj problem se rešava proširenjem skonfiguracije za JOŠ JEDNU BUSTER PUMPU koja se pali prilikom ispiranja sistema. Pumpe su dosta skupe a ponekad jednostavno NEMA DOVOLjNO VODE U CEVIMA pa ni sa njima ne rešavamo ovaj problem.

Ako obratite pažnju na deferizatore vode drugih proizvođača, videćete da su HYDROLUX deferizatori oko 80-120% efikasniji odnosno DUPLO MANjI što dodatno štedi novac kroz troškove "bačene" vode prilikom redovnih ispiranja. U 99% slučajeva NE ZAHTEVAJU DOZIRANjE OKSIDANSA poput hlora (osim ukoliko voda ne sadrži bakterije), RADE ISPOD Ph 6.5-6.8 što je standard za većinu konkurentskih medija!

 

Ukoliko su vam neophodni uređaji za otklanjanje Gvožđa, Mangana, H2S ili Aresna većih kapaciteta, pogledajte proizvođačku brošuru ili nas kontaktirajte. Ukoliko voda sadrži povišene vrednosti Arsena il H2S neophodno je doziranje ili dodavanje neke vrste oksidansa poput hlora isl.

A backwashing filter, often called an iron filter or oxidizing filter, is the most widely used system for removing iron and sulfur. Iron filters work by oxidizing the iron and/or sulfur and then filtering it out through the media bed. The best medias at removing these contaminants are medias that are manganese dioxide based or coated media. Birm is coated with less than a half percent of manganese dioxide which is why it is limited in application.

Greensand Plus is a little higher in manganese dioxide and Filox, Pyrolox and MangOx are 60 to 80% manganese dioxide. However, the most common reasons for filter failure are a lack of flow in backwash or a lack of frequency of regenerations. Filtration using oxidation is the most common method of iron removal. Oxidizing filters use an oxidizer such as ozone, oxygen, chlorine or hydrogen peroxide to boost the oxidizing properties of the water being treated and allow for better iron removal. Iron filters and sulfur filters have been used for many years in the water treatment industry with varying levels of success or maybe we should say “unsuccess.” The biggest problem with most iron filters is simply the weight of the media, because the heavier the media, the more water and pressure it takes to backwash, and the fact of the matter is that many wells do not have the capability of producing such a flow of water.

Medias like Filox, Pyrolox and MangOx weigh from 114 to 125 pounds per cubic foot. For example, to backwash a 1.5 cubic foot tank (10” x 54”) of Pyrolox or Filox or any typical manganese dioxide-based media, would require 15 Gallons Per Min (GPM). Backwash and rinse time can be up to 20 minutes.

Do the math! Yikes! That’s wasting a lot of water. Some systems waste up to 300 gallons of water per regeneration and most need to backwash daily or at least every other day. We think that is simply wasteful! Old-style iron filters and sulfur filters are rapidly becoming obsolete due to their inherent inefficiency and massive wasting of water, to say nothing of the fact that many really don’t work very well.

Additionally, many use either potassium permanganate or chlorine to regenerate as an oxidizer. Potassium permanganate dissolves into water and gives it an intense pink or purple color, and will forever stain things it comes into with if the concentration is too high. Potassium permanganate is generally held in a tank with a small amount of water at the bottom. The problem is these tanks frequently overflow, and it’s easy to spot the homes where this has occurred by the brown and purple stains all over which cannot be removed – EVER!

Additionally, potassium permanganate is a toxic chemical and can cause serious eye injury, is a skin and inhalation irritant, and can be fatal if swallowed. For that reason, most people do not want it in their water. Over the past several years, potassium permanganate has fallen out of favor with savvy water professionals. Chlorine is also used as an oxidizer by many companies because it is easier to handle and doesn’t leave stains like potassium permanganate. However, chlorine is more insidious than it is dangerous in that during oxidation, disinfection by-products (DBP’s) are created. Trihalomethane (THM’s) are one of these DBP’s and are known carcinogens (cancer-causing agents). If you use chlorine, then you will need to add a backwashing carbon filter after the iron or sulfur removal system to remove the chlorine and disinfection by-products.

Then we have Katalox Light… To begin with, Katalox is a revolutionary new media developed in Germany. Katalox Light is engineered with a unique manganese dioxide coating technique on ZERSORB (which is a very lightweight media). It has a manganese dioxide coating of 10%. Katalox Light is ANSI/NSF 61 Certified for drinking water applications and has met the ANSI/NSF 372 lead-free compliance. The Katalox Light media has a very high surface area which filters down to three (3) microns and immediately stops oxidized or precipitated forms of Iron, Manganese and Hydrogen Sulfide from passing into the water stream. It generally needs backwashed every 4 to 7 days, unlike other heavier media that requires daily backwashing. In cases where heavy iron or heavy sulfur exists, we utilize chlorine as an oxidizer only during the backwashing process. In addition, Katalox Light and chlorine can successfully remove radium, uranium, selenium, arsenic, zinc, copper and lead, as well as other radionuclides. In order to do this, iron must be present to facilitate the process. In certain cases, the pH must be raised or lowered, depending upon the water chemistry and contaminants. In short, Katalox Light is a revolutionary media that is changing the way iron and sulfur are removed from water.
