BIG Series (Blue Inline Gasketed)
Precision, gasket-sealed in-line filters for leak-free, consistent filtration. Designed for any pressurized water system — agricultural, municipal, industrial, or hydropower — delivering durable stainless-steel performance with manual or automated cleaning.
BIG = Blue Inline Gasketed
The BIG Series is CTC Waterworks' flagship inline pressure filter platform. Versatile inline pressure filter supporting multiple cleaning technologies across all industries. Protect pumps, valves, heat exchangers, and emitters with reliable stainless-steel construction. Choose your filter body size, select your screen type and mesh, then add the cleaning technology that fits your water quality and maintenance preferences.
Three Cleaning Approaches Available
Supports Manual, Semi-Automatic (BIF & MVC), and Fully Automatic (RAB & AVC) cleaning options.
Why Choose BIG Series?
Continuous Service
On-line cleaning options mean no system shutdowns. Flow continues while cleaning happens automatically or with simple hand-crank operation.
Broad Size & Flow Range
Available in 2" through 8" connection sizes and larger custom configurations. Handles flows from small drip zones to high-capacity mainlines.
Serviceable Components
Standard mesh screens and perforated plates with quick-access design. Replace or change screen types in the field without special tools.
Highly Configurable
Adaptable for drip irrigation, micro-sprinklers, center pivots, intake polishing, and industrial applications. One platform, multiple uses.
Choose Your Cleaning Technology
BIG Series bodies support both Brush and Vacuum cleaning systems. Start with manual operation and retrofit to automatic later, or specify automatic from day one.
Brush Cleaning
Mechanical Scrubbing Action
Rotating brush assembly scrubs the screen surface to remove fibrous debris, organic matter, and algae. Available in manual hand-crank or fully automatic sensor-triggered operation.
Available Options:
Vacuum Cleaning
High-Suction Backflush
Vacuum scanner creates powerful suction to extract heavy debris through rapid backflush cycles. Ideal for sand, silt, and high solids loading with minimal water loss.
Available Options:
Cleaning Options
Choose the cleaning method that best fits your operation, water quality, and maintenance preferences.
Manual Cleaning
- •Lowest upfront cost
- •Simple operation with no power requirements
- •Requires shutdown and manual screen removal
- •Best for low solids and infrequent cleaning needs
Semi-Auto (BIF/MVC)
- •Brush-In-Filter or manual vacuum/brush combo
- •Reduces downtime significantly
- •Minimal power requirements
- •Ideal balance of cost and convenience
Fully Automatic (RAB/AVC)
- •Self-cleaning brush or vacuum/brush system
- •Continuous service without interruption
- •Ideal for high solids and remote locations
- •Automated operation with minimal oversight
Cleaning Assembly Availability
Cleaning assemblies (BIF/MVC/RAB/AVC) availability varies by model and size. See Parts & Accessories for complete compatibility information.
Common Applications Across Industries
BIG Series filters serve diverse water systems across agriculture, municipal, industrial, and hydropower sectors
Irrigation Systems
Drip, micro, pivot, and solid-set systems for orchards, vineyards, and row crops
Municipal Water & Wastewater
Raw-water intake, pre-filtration, and pump-station protection for treatment facilities
Industrial Process Water
Food & beverage, packing-line wash water, coolant filtration, and rinse-water recovery
Hydropower & Dams
Intake protection with fish-safe screen configurations meeting NOAA/WDFW criteria
Infrastructure & Construction
Reuse water filtration, dewatering, and sediment control for large-scale works
Intake & Canal Filtration
Surface-water intake and canal protection for pumps, membranes, and mechanical systems
Engineered for Any Water Source
BIG Series filters perform reliably in agricultural, municipal, industrial, and hydropower applications. From irrigation networks to process-water loops and dam intakes, these stainless-steel filters provide durable, low-maintenance solids removal wherever clean water matters.
Scalable Bank Configurations
BIG Series filters can be installed as individual units or arranged in parallel filter banks for high-flow applications. Multiple filters provide redundancy, allow staged cleaning without flow interruption, and scale capacity to match system demand.
Parallel Operation
Multiple filters distribute flow and provide backup capacity for continuous operation
Staged Cleaning
Clean one filter while others remain online—no system shutdowns required
Future Expansion
Add filters to existing banks as water demand increases over time
Filter Bank Configuration
Multiple BIG Series filters arranged for high-flow applications
