Pulp Ozonation

SNIACE S.A. is a pulp mill located in Torrelavegas, Spain (near Santander), with an annual production capacity of 66,000 tons of dissolving pulp from Eucalyptus. Forty percent of the pulp is used in its own viscose plant, and the remaining 60% is sold to the market.

SNIACE’s cellulose is used to make various products, such as viscose fibers for the textile industry; acetate for the chemical industry; sanitary towels, insulators and cellulose film for industrial applications; and cloths and sponges for household use.

Reuse & Renewal

With diminished rainfall, a depleted aquifer basin, near-empty recharge ponds and an earthquake-vulnerable aqueduct system, the Santa Clara Valley Water District (SCVWD) in San Jose, Calif., required additional water supplies to maintain regional economic vitality for its growing community.


In the Ozone

Enactment of the Long Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectant and Disinfection Byproduct Rule (D/DBPR) will require both large and small drinking water utilities to reduce total organic carbon (TOC), cryptosporidium, and disinfection byproducts (DBPs) in the treated drinking water distributed to the public. Ozonation has helped prepare a North Carolina Water Treatment Plant (WTP) to comply with these federal drinking water regulations and overcome long-standing taste and odor problems of its raw water drawn from the B.

Getting Off the Ground

Clovis is a city with a population of around 97,000 in Fresno County, Calif. The city is 6.5 miles northeast of downtown Fresno. Until the early 1970s, groundwater was the sole water source for the residents of Clovis. Well water was used for irrigation and industrial use, as well as drinking water. As the population grew in Fresno County, ground water levels dropped and wells began drying up. To meet the growing water needs, the city of Fresno decided to recycle water being processed at its wastewater treatment facilities.


Hope for the Future

The city of Carmel, Ind., located north of Indianapolis, owns and operates Carmel Wastewater Treatment Plant (WWTP), which treats sanitary waste from Carmel, Clay Waste District and Westfield Utilities. When the plant became unable to meet the growing demands of the 70,000-person population area, the city decided to increase Carmel WWTP’s capacity to meet current and future water treatment demands.


Acquiring the Taste

Prairie du Sac, a village of 3,400 located in south central Wisconsin, began its journey to UV disinfection when it was selected as one of 14 communities in the state to participate in a $2.3-million, U.S. Environmental Protection Agency (EPA)-funded study focusing on the role of drinking water in childhood illnesses. The Marshfield Clinic Research Foundation in Marshfield, Wisc., conducted the Wisconsin Water and Health Trial for Enteric Risk.

Cheaper Is Not Always Better

Summerville, Ga., a small city in the northwestern part of the state and the seat of Chattanooga County, built its 2-mgd wastewater treatment plant in 1967. It was designed to handle the flow from a developing municipal collection system that now serves 1,860 connections.
