Q1: What types of fungi does Grotan WSplus effectively control?
A: Grotan WSplus is a broad-spectrum fungicide designed to inhibit the growth of common spoilage and contamination fungi in industrial water-based systems, including Aspergillus, Penicillium, Cladosporium, and various yeasts. Its performance is optimized in recirculating cooling water, process water, and preservative applications where microbial stability is critical.
Q2: Is Grotan WSplus compatible with common water treatment additives such as corrosion inhibitors and scale preventers?
A: Yes — Grotan WSplus has been formulated for compatibility with a wide range of non-oxidizing biocides, dispersants, and conventional corrosion and scale inhibitors used in industrial water treatment. Compatibility testing under site-specific conditions is recommended prior to full-scale integration to confirm stability and efficacy.
Q3: How is Grotan WSplus typically dosed in industrial water systems?
A: Dosage is application-dependent and influenced by system parameters such as water composition, temperature, organic load, and microbial challenge. It is generally applied at low concentrations via continuous or intermittent feeding, with typical use levels ranging from 0.1% to 2% by weight of active ingredient in the treatment solution — precise rates should be determined through controlled efficacy trials.
Q4: Does Grotan WSplus require pH adjustment or special handling during storage and application?
A: Grotan WSplus is supplied as a stable aqueous dispersion and performs effectively across a broad pH range (approximately 5–9). It does not require pre-neutralization but should be stored in a cool, dry place away from direct sunlight and strong oxidizers. Avoid freezing, and ensure adequate mixing during dilution to maintain uniform dispersion.
